Need to install a Dynomax Bullet Muffler as a resonator in my I-pipe due to the dreaded Mac ORY drone.Problem is that I have a SLP stainless steel I-pipe & the Dynomax is plain steel.The muffler shops here tell me they can't weld it but would cut the I-pipe and clamp it in.Just seems too flimsy to me.Has anyone done this (Clamps) or have an opinion about it?
